The generally used methods like high-pressure liquid chromatography (HPLC) and other coupled techniques are not just time-consuming but also expensive and often destructive. To facilitate real-time measurement of active ingredient concentration, an alternative non-destructive machine vision and artificial intelligence-based system was tested, that implements ultraviolet (UV) illumination. With this technique the concentration of the active pharmaceutical ingredient containing fluorophore groups can be studied due to the different light emission of the different active pharmaceutical ingredient concentrations. However, to facilitate the practical application of this novel non-destructive and system, it is essential to determine its limit of detection (LoD) and limit of quantification (LoQ). In this study we aimed to study the LoD and LoQ of UV illumination fluorescent imaging of tablets using levofloxacin as the active pharmaceutical ingredient.

In general, vectors containing a mixture of the cationic lipids DOTAP and DODAP showed enhanced transfection efficacy compared to their counterparts without DODAP. The incorporation of AF in the vectors formulated with SLNs prepared with DOTAP and DODAP by hot-melt emulsification significantly improved the efficacy to induce the expression of α-Gal A in hepatocytes in vitro compared to the control without AF. However, the administration to Fabry mice did not result in a significant increase in enzyme activity.

This study investigates the probabilistic design space to explain the process operability and performance reliability using a Bayesian approach for a fluid bed drying process. We initially develop a Bayesian model by integrating a surrogate-based predictive model with embedded uncertainty quantification of material variability. Subsequently, employing a grid search-based technique to discretize the operational variable domain facilitates the exploration of the probabilistic DS to meet the specified product quality requirements. Meanwhile, optimization is employed to obtain the maximum DS region and enhance its operability.

Heat released from a vial undergoing solidification may be transferred to neighbouring vials, impacting their thermal profiles and altering the distribution of the nucleation temperature and the freezing rate within the batch. This study characterised thermal coupling in interacting and non-interacting loading configurations. These estimations were used as input in a simple 1D mathematical model to assess the effect of thermal interactions on the freeze-dried product morphology. Thermal interactions strongly impacted the predicted nucleation temperature, especially for late-nucleating vials, and the freezing rate. The combined effect of thermal coupling on nucleation temperature and freezing rate resulted in different frozen product morphology. Heterogeneity within a batch of interacting vials was higher compared to non-interacting vials, leading to broader pore size and drying time distributions, in agreement with experimental data.

These benefits include increased flexibility, higher product output, enhanced quality assurance through better monitoring techniques, and more consistent distribution of Active Pharmaceutical Ingredients (APIs). Despite these clear advantages, there is a lack of research focused on the simultaneous optimisation of multiple sub-processes in continuous manufacturing. This study explores the optimisation processes of continuous pharmaceutical production, explicitly targeting the production of mefenamic acid using wet milling (WM) and mixed-suspension mixed-product removal (MSMPR). We employ data-driven evolutionary optimisation algorithms to address these many-objective optimisation problems (MaOPs). High-fidelity model-generated data generated via the General Process Modelling System (gPROMS) is subsequently utilised to develop simpler surrogate models based on the Radial Basis Function Neural Network (RBFNN). This enables very fast simulations, suitable for use with computationally intensive machine learning algorithms. Utilising evolutionary optimisation algorithms, these models are used for model-based process optimisation. The efficacy of the MaOP approach is evaluated using a range of numeric and visual optimisation performance indicators. Our findings underscore the viability of integrating high-fidelity and surrogate models to discern functional relationships between dependent variables (objective functions) and independent variables (decision variables), providing a robust framework for process optimisation within the pharmaceutical domain. The approximated solutions are, on average, 58% better than the solutions obtained from Latin hypercube sampling. The chosen optimal solutions can form the basis of parameter setting in upcoming experimental campaigns.

In addition, PredicDiff™ delivers the system’s diffusion- and partition coefficients and the equilibrium concentration. Three case studies are presented: 1) interpolation of ε-caprolactam from a polysulfone disconnector from 24 h to 2 h, 2) adjustment of the diffusion of ε-caprolactam from a polysulfone disconnector from 40 °C to 21 °C, and 3) extrapolation of 2,4-Di-tert-butylphenol from an ultra-low-density polyethylene (ULDPE) bag from 70 to 90 days. In addition, the usability of PredicDiff™ for inter- or extrapolation of an unidentified extractable from a silicone tubing is shown. In the first case, after a contact time of 2 h, the concentration and hence, also patient exposure to ε-caprolactam is reduced by 70 % in comparison to the extractable value after 24 h. In the second case, further adjustment based on contact temperature (21 °C vs. 40 °C) gives a total reduction of 87 %. In the third case, the concentration and therefore, also patient exposure to 2,4-Di-tert-butylphenol increases by 2.6 % if storage is prolonged from 70 days to 90 days. PredicDiff™ has no limitations on the types of extractables (including those whose identities are not elucidated) or concentration ranges. Based on the remodeling of diffusion curves from literature and the calculation of extractables amounts from studies (analytical data), it is shown that PredicDiff™ provides reliable results within an acceptable range of uncertainty.
